While working for Standard Knitting (a client of Gratzer's and Clark's), David wrote a report generator called dComp that would allow up to six related data files to be in use at one time and run faster than the slow, dBase II.

The published reference manual for VP-Info was over 900 pages and the program was distributed in an extra thick back cover which was an innovation for all Paperback Software products at that time.

VP-Info can read and write any type of dbf files (e.g. dBase II, III, IV, Clipper) at the same time.

On modern computers with fast SSDs, the speed increase is not as noticeable as compared to older PCs with removable discs.

[10] VP-Info, and subsequent SharkBase versions, can run on 32-bit or 64-bit Windows, using a virtual machine or emulator to provide a usable environment.

It has been reported that both VP-Info and Shark run under the latest Windows versions using either vDOS,[11] or DOSbox-X,[12] both recent forks of the earlier DOSBox MS-DOS emulator,[13] and also on multi-user/multi-tasking systems with NetBIOS over TCP/IP such as PC-MOS/386.

The vDOS & DOSBox-X emulators offer access to all hardware output (printer) ports on the hosting Windows systems.
